Can actions and reactions be played before or after "when attack" and "when defend" effects resolve?

Ruling: Only reactions can be played in response to "when I attack/defend" triggers. After those effects resolve, both actions and reactions can be played (when no chain is present).

Sequence:

• "When I attack/defend" effects trigger
• Only reactions can be played in response to these triggers
• After the "when I attack/defend" effects resolve, actions and reactions can be played (if no chain is present)
